The index finger swept across the screen, Jiang Feng's fingertips lightly tapped on the center of the screen, and the snowflake-white pictures were removed from the screen.

"Brain, collect the cause of the destruction of the detector."

【Data Recovery......

Lines of pale blue text swept through the middle of the screen, all reflected in Jiang Feng's pupils, listing the information collected by various probes from the small secret realm.

“…… There is a specific cycle of change in the concentration of mana elements in the small secret realm, which is between thirteen and fifteen days, of which the first three days are the period of mana depletion, and the last three days are the period of high tide of mana...... At the end of the last day, the mana element will reset to zero in an instant, and the journey will be reincarnated. ”

"I see, in this way, the secret feast once every five years should happen to be in time for the middle period of magical peace."

"The first three days and the last three days were fine, but the real fatal thing was the zero day after the end of a reincarnation, which lasted between one and two days. During this time, the magic elements of the entire subspace will return to zero point, which is almost fatal for wizards, because there is no magic element to use at all, and those powerful magical beasts living in the secret realm, even if they do not rely on magic, can rely on their strong physical strength to tear weak wizards to pieces. ”

"No wonder no one can stay in this secret realm for five years...... Not to mention five years, I'm afraid half a month is already the limit. Unless it's a martial artist with a physical element, I'm afraid no one can hold on to this. ”

Thinking of this, Jiang Feng shook his head secretly.

It seems that this secret realm is not an ordinary difficult to serve, it is even more troublesome than calculating the time of the eldest aunt, especially the zero period after the end of a cycle can not find a pattern at all, and there is no way to simply measure the "safe period" of this secret realm through experience.

However, fortunately, there is a detector that can monitor the changes in the concentration of magic elements in the secret realm in real time.

As long as he carefully avoided Day Zero, the entire secret realm was under his control, and after establishing a stable teleportation channel, he could open this portal at will without waiting for the time of the arcane temple.

He kept these discoveries in his notebook, and although he could access them at any time through the Brain's database, his apprentice did not have that condition.

This information allows them to avoid some detours and avoid some unnecessary casualties.

"Now, is it time to start experimenting?"

Seeing that the hourglass-shaped mana trough was gradually filled with a light blue light, Jiang Feng reached out and pressed it on a red valve, gently pushing it forward.

The inscriptions carved on the stone slabs were instantly connected, and the magic stones entwined by wires, like capacitors connecting circuits, bloomed with a light blue light.

Looking at the gradually distorted space between the two huge doorposts, Jiang Feng reached out and took out the Galaxy K6, and at the same time put the bursting potion and the ignition potion next to him, and waited to observe the changes in the portal.

Space jumps are always full of uncertainty, especially with such one-way open passages.

Not only may the demonic beasts in the opposite space move to this side along the randomly opened passage, but some monsters wandering in the void may also invade this world along this unstable passage.

Jiang Feng had consulted relevant documents in the library of the Vallan Alchemist Association, and in ancient times, when the elven clan was studying the dwarven clan's inscription technology and inscription portal, he had summoned the Void Demon.

There is even a theory that the reason why the Chaos Faith is spreading in this world is related to a failed experiment of the Elves against the portal......

For possible abnormal situations, Jiang Feng was ready to close the portal at any time. Combined with the witchcraft array and defensive dotted laser array he left in the laboratory, even if a five-star wizard appeared in front of him, he was fifty percent sure of killing him!

【Portal Charging...... Progress 71%】

【…… Progress 83%】

The distortion of space became more and more violent, and the ripples spread outward, like a twisted vortex, pulling the light in the laboratory.

Suddenly, the twisted vortex paused, and the clockwise rotating ripples suddenly turned into counterclockwise rotation, and the parameters on the screen jumped wildly, with a capital [Warning! Pop up in the center of the screen.

At the same time, the electronic sound of warning came from the brain.

[Warning, unidentified energy body detected passing through the space channel......]

The moment the alarm sounded, Jiang Feng's eyelids jumped wildly.

, the first time I opened the dimensional wall, I brushed out the void invasion, I won't have such a black face!

"Click——!

A tooth-aching cry floated from the portal, and a trace of cold air filled the air, obviously the temperature in the room did not change at all, but Jiang Feng felt a trace of cold that penetrated deep into the bone marrow.

A pair of powerful arms stretched out from the dark blue swirls between the doorposts, dark blue transparent mist-like shells, and the real form could not be seen. Streams of electricity like silver snakes were like blood vessels, passing under the mist-like body, crystalline stone slabs floating around it like armor, and from the surging spiritual energy, Jiang Feng read a trace of undisguised hostility.

The hostility is not directed at any particular individual, but at all carbon-based organisms!

It's the Void Hunter!

Jiang Feng's pupils shrank slightly.

"Click——!

The second howl sounded, and the spirit-like creature struggled to break free from the shackles of the portal's gravity, and pounced on Jiang Feng's side unabated.

Without hesitation, Jiang Feng quickly activated the laser point defense array in the laboratory, and the dots of red light bloomed from above the ceiling, and a series of dazzling laser beams were suddenly launched, hitting the crystalline shell, dispelling the cold in the laboratory in an instant, and even the surrounding air was heated by the scorching beam.

"Click——!!!

The crystalline stone slab was burned into a red color like a soldering iron, and the Void Hunter let out a painful howl, but the momentum of the attack really did not change at all, and the bucket-thick right hand clenched into a fist and slammed into Jiang Feng's side.

"Boom !!"

Circles of transparent ripples swung out, and the right hand that slammed into the defensive barrier was like a battering ram on the city wall, and the floor of the laboratory trembled a little.

With just such a blow, most of the energy of the defensive circle was consumed!

A drop of cold sweat crossed Jiang Feng's forehead, and his right hand holding the valve hesitated for a moment, and finally a trace of firmness flashed in his eyes.

Fight!

If the portal is closed, the hundred magic stones that have been put into the portal will be lost, and since this Void Hunter has already set his sights on this plane, even if he waits until tomorrow to open the portal, the result will be the same.

No longer hesitating, Jiang Feng took out a box of bone powder ground from the Jewel Dragon's ribs from the side and spilled it fiercely towards the Void Hunter.

A dagger of glittering light rained down on the Void Hunter like a cursor shot from a phase cannon.

Not only undead creatures, but all spirit creatures are also afraid of the scorching of light-attribute witchcraft.

With a low cry of pain, the Void Hunter raised his right fist, blocking the flying cursor.

Although it did not cause serious damage to the Void Hunter, it greatly restrained his attack, and with the intermittent firing laser beams on the ceiling, it was enough for Jiang Feng.

"It was originally a magic circle prepared for a three-star wizard-level threat, but now it's cheaper for you."

The last incantation was spit out, and Jiang Feng's index finger pointed forward.

A huge circular circle enveloped the portal and the open space between him.

The Void Hunter was naturally inside, feeling the surging magical elements around it, and it gradually felt the fear, desperately trying to break free from the dagger rain and laser beams, but it was too late.

A green poisonous mist floated from the floor, quickly filling the entire area covered by the circle. Under the restraint of sorcery, the entire poisonous mist was confined to the area of a single cylinder, and not a single trace of gas leaked out.

Rotten Poisonous Mist!

Neither matter nor disembodied souls can resist the erosion of this poisonous mist.

The flying cursor had stopped, and the laser beams on the ceiling had stopped, as there was no need to attack anymore.

Leaning on the experimental table, Jiang Feng breathed a sigh of relief, and his afterglow swept towards the screen, and the passage of the portal had stabilized. Although there were many twists and turns, the experiment was a success.

The Void Hunter in front of him was gone, replaced by a sorcery circle filled with poisonous mist. From the outside, it looks like an emerald stone pillar.

No creature can survive it, not even enemies from the Void......
